	Bazeries cylinder - Wikipedia, the free encyclopedia
		The Bazeries cylinder is a simple cipher machine originally invented by American President Thomas Jefferson in the 18th century, but did not come into wide use until it was reinvented by Commandant Etienne Bazeries, the conqueror of the Great Cipher, a century later.
		A Bazeries cylinder consists of a set of roughly 20 to 30 numbered discs, with a different cipher alphabet on the edge of each disc, and a hole in the centre of the discs to allow them to be stacked on an axle.
		The Bazeries cylinder was the basis for the US "M-94" cipher machine, which was introduced in 1922 and derived from work by Parker Hitt.

		He is best known for developing the "Bazeries Cylinder", an improved version of Thomas Jefferson's cipher cylinder.
		In 1863 he enlisted in the army, and fought in the Franco-Prussian War, where he was taken prisoner, although he later managed to escape disguised as a bricklayer.
		Bazeries continued his cryptanalytic work there even after he retired from the Army in 1899, assisting in solving German military ciphers during World War I.

	Cryptologia: MAN IN THE IRON MASK - ENCORE ET ENFIN, CRYPTOLOGICALLY, THE
		ABSTRACT: Bazeries' proposed solution to the mystery of the Man in the Iron Mask is made more doubtful by a hitherto overlooked entry in a standard work of cryptlogy and by its confirmation by a later investigation.
		Bazeries, the examination of the ciphers of Louis XIV in the Historical section of the Ministry of War enabled us to determine that none of the variants of the cipher of 1691 included the word mask, which is moreover not a word usually liable to figure in a repertory consisting of only 587 groups.
		Bazeries in favor of his solution appearing rather to weaken it, we have been led to think that the solution was doubtful if not erroneous.

		Etienne Bazeries (1846-1931) was a French military cryptanalyst active between 1890 and the First World War.
		He is best known for developing the "Bazeries Cylinder", an improved version of the Jefferson cipher cylinder (which was later refined into the US Army M-94 cipher device).
		In the 1890s he broke a famous nomenclator system called the Great Cipher, created by Rossignol in the 17th century.

		He and his son, Bonaventure Rossignol, were soon appointed to prominent roles in the court.
		Together, the two devised a code which used 587 different numbers that was so strong it baffled cryptanalysts for centuries until Commandant Étienne Bazeries managed to break the cipher around 1893, realizing that each number stood for a French syllable rather than single letters as traditional codes did.
		He guessed that a particular sequence of repeated numbers, 124-22-125-46-345, stood for "les ennemis" (the enemies) and from that information was able to unravel the entire cipher.

	The Bazeries Cylinder (Site not responding. Last check: 2007-10-22)
		The alphabets on the M-94, a version of the Bazeries cylinder made from aluminum, and used by the U.S. during the Second World War, were chosen to be part of a Latin square to be more resistant to a de Viaris attack.
		The Bazeries cylinder relies on the input plaintext being plaintext, with some redundancy, so that it can be found.
		Of course, if one allows expanding the text with an extra letter, or using a pre-arranged scheme to pick the ciphertext row, variations of the cipher method can be designed without this limitation, and therefore useful for the subsequent encipherment of ciphertext.

	[5.0] The Mechanization of Ciphers
		A Bazeries cylinder consists of a set of roughly 20 to 30 numbered disks, with a different cipher alphabet on the edge of each disk, and a hole in the center of the disks to allow them to be stacked on an axle.
		In 1914, Hitt had experimented with the Bazeries device, building one prototype using slides on a wooden frame, with the cipher alphabets printed twice consecutively on the slides, and then another using disks of wood.
		One major weakness of the Bazeries cylinder is that the offset from the plaintext letter to the ciphertext letter for the cipher alphabet on each disk will be exactly the same.

		Around 1893, Etienne Bazeries managed to break the Cypher and in so doing discovered a contemporary reference to The Man in the Iron Mask who was, it thus appeared, not actually only legendary.
		Unfortunately, the message (regarding his transfer from one prison to another) did not shed any light on his identity or crime.
		Bazeries continued his cryptanalytic work there even after he retired from the Army in 1899, assisting in solving German military ciphers during World War I. He retired in 1924, aged 78.

		But Jungs arguments, though strong destructively against the Mattioli theory, break down as regards any valid proof either that the prisoner arrested at Perontie was a Bastille prisoner in 1673 or that he was ever at Pignerol, where indeed we find no trace of him.
		Another theory, propounded by Captain Bazeries (La Masque de fer, 1883), identified the prisoner with General du Bulonde, punished for cowardice at the siege of Cuneo; but Bulonde only went to Pignerol in 1691, and has been proved to be living in 1705.
